I own a second hand Swift petrol. Bought in Dec 2009. Just few good things about SWIFT. Gives a good mileage with AC. It gives me a good mileage of 18 plus in highways with AC running almost. In fact, sometimes I keep driving at constant 100 km/hr. I travel to Chennai from Bangalore and almost reach it in 5 hrs. Swift is really stable one while driving at high speeds in HIGHWAYS. The vehicle responds to your commands. For city driving I get 12 km/litre with AC running that too in Bangalore traffic. Just I love my car. Two things I would like to HIGHLIGHT here:
1) Mileage 18+ in highways and 12 in city with full AC is reasonably good.
2) Stability of the vehicle at high speeds in highways is good.
